Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the app or marketing strategy. Has there been any significant update to the app or change in marketing campaigns in the last 30 days?

Why it matters: Recent changes often correlate with sudden metric shifts. Expected answer: Yes, we launched a new onboarding flow two weeks ago. Impact on approach: If confirmed, I'd focus on analyzing the new onboarding process.

• Considering user segments, I'm wondering if this drop is uniform across all user types. Are we seeing the 30% drop consistently across different user segments (e.g., age groups, regions, device types)?

Why it matters: Identifying affected segments can pinpoint specific issues. Expected answer: The drop is more pronounced in the 25-34 age group and on Android devices. Impact on approach: I'd prioritize investigating Android-specific issues and factors affecting younger users.

• Given the nature of Zwift's product, I'm curious about seasonality. Is this drop aligned with any historical seasonal trends in user sign-ups?

Why it matters: Seasonal patterns could explain sudden changes in user behavior. Expected answer: We typically see a slight dip in summer, but not to this extent. Impact on approach: I'd factor in seasonality but look for additional causes given the severity of the drop.

• Thinking about the competitive landscape, has there been any significant move from competitors or changes in the market recently?

Why it matters: External factors can significantly impact user acquisition. Expected answer: A major competitor launched a promotional campaign last month. Impact on approach: I'd analyze the competitor's offering and our market positioning.
